Searches for the lepton number violating decay and the lepton flavor violating and decays are reported using data collected by the NA62 experiment at CERN in 2017-2018. No evidence for these decays is found and upper limits of the branching ratios are obtained at 90% confidence level: , and . These results improve by 1 order of magnitude over previous results for these decay modes.
The alliance between the seemingly disparate Lebanese Christian party Free Patriotic Movement and the Shi’a organization Hezbollah has survived many local and regional upheavals since the signing of the memorandum of understanding (MoU) in February 2006. The pact was strengthened after the 2006 summer war and has stood for 15 years - despite political assassinations and low-intensity conflict in L
Metal-based shielding plays an important role in the attenuation of harmful and unwanted radiation at an accelerator-driven spallation neutron source. At the European Spallation Source, currently under construction in Lund, Sweden, metal-based materials are planned to be used extensively as neutron guide substrates in addition to other shielding structures around neutron guides. The usage of metal
Community radio can support the process of having a voicein one’s community as a part of civic action, and promotecommunity dialogue. However, older adults are underrepresentedas producers of community radio shows in the UK,and face different challenges to their younger colleagues. Byworking within the radio production group of an existingorganisation of older adults, we identify the motivations a
Recently, Peritoneal Surface Oncology Group International (PSOGI) developed a novel comprehensive treatment consisting of cytoreductive surgery (CRS) and perioperative chemotherapy (POC) for the treatment of peritoneal metastases (PM) from gastric cancer with curative intent. This article reviews the results of this treatment and verifies its indication. In this strategy, peritoneal cancer index (
We propose a non-intrusive reduced basis (RB) method for parametrized nonlinear partial differential equations (PDEs) that leverages models of different accuracy. From a collection of low-fidelity (LF) snapshots, parameter locations are extracted for the evaluations of high-fidelity (HF) snapshots to recover a reduced basis. Multi-fidelity Gaussian process regression (GPR) is employed to approxima
In this paper, goal-oriented error estimation for Timoshenko beams on Pasternak foundation, which involves double shear effect, is performed. The constitutive relation error (CRE) estimation is used in finite element analysis (FEA) to acquire strict bounds on quantities of interest. Due to the coupling of the displacement field and the internal force field in the equilibrium equations of the beam,
On the basis of the dual variational formulation of a class of elliptic variational inequalities, a constitutive relation error is defined for the variational inequalities as an a posteriori error estimator, which is shown to guarantee strict upper bounds of the global energy-norm errors of kinematically admissible solutions. A numerical example is presented to validate the strictly bounding prope
Cyclodextrin-based nanosponges are promising materials for heterogeneous catalysis due to their inherent synthetic versatility, tunable porosity and nontoxicity. In this work, a primary amine-rich β-cyclodextrin nanosponge was synthesized via click imine condensation reaction between 1,6-hexamethylamine-functionalized β-cyclodextrin (CDAM) and glutaraldehyde (GLT) to afford CDGLAM, in mild conditi
In this paper, perforated shear connectors (perfobond), used extensively in steel-concrete composite (SCC) beams, are implemented in timber-concrete composite beams (TCC) and experimentally investigated. In contrast to its original use, the perfobond connector is connected with an adhesive to the timber beam while welded in the SCC solution. On the concrete slab side, connection is achieved using
Among the most advanced techniques for quality control, image processing and optical methods areprominent because of their precision and versatility. These methods often involve analyzing specklesgenerated by coherent laser illumination because coherent light provides detailed and accuratemeasurement capabilities. In speckle metrology-based techniques, the accurate measurement ofspeckle displaceme
This commentary discusses the role of increasingly artificial intelligence-infused big tech platforms in facilitating and normalising high-emission lifestyles and consumption practices. It introduces the notion of algorithmically facilitated emissions to initiate a shift from a logic of ‘climate collapse by design’ to a logic of ‘emissions reduction by design’. Reducing consumption-based emissions
In this study, we investigate integrating eye tracking with auditory attention decoding (AAD) using portable EEG devices, specifically a mobile EEG cap and cEEGrid, in a preliminary analysis with a single participant. A novel audiovisual dataset was collected using a mobile EEG system designed to simulate real-life listening environments. Our study has two main objectives: (1) to use eye tracking
The maximum drawdown of a stochastic process is the largest peak-to-troughdecline observed over a given horizon [0, T]. Using arguments from extremevalue theory, we derive the limiting distribution of the maximum drawdown fora Brownian motion with positive drift as T → ∞. We show that, after suitablecentering and scaling, the maximum drawdown converges in distribution to theGumbel law.
OBJECTIVES: The Sepsis-3 definition states the clinical criteria for sepsis but lacks clear definitions of the underlying infection. To address the lack of applicable definitions of infection for sepsis research, we propose new criteria, termed the Linder-Mellhammar criteria of infection (LMCI). The aim of this study was to validate these new infection criteria.DESIGN: A multicenter cohort study o
Prurigo nodularis (PN) is a chronic, itchy, inflammatory skin condition that negatively affects quality of life. A study was undertaken to investigate the healthcare utilization, including treatment patterns and direct costs for specialist care, for PN in Sweden. Linkage cohorts were created from national Swedish patient and prescription registers, and the cost-per-patient database of PN adults in
